The Several Meanings of “Positive”

Abstract

Wiegand and Geller propose that the salient role of positive reinforcement in behavior analysis should enable a melding of behavior analysis with developments and concepts that have appeared under the banner of “positive psychology.” However, as is true of many words, the term positive has more than one meaning, and the positive of positive reinforcement is not the same as the positive of “positive psychology.” The latter is parasitic upon the vernacular, as “nice” or “desirable,” whereas the former is analogous to the algebraic “add” as when an action produces the appearance (as contrasted with the removal) of some event. The distinct meanings become clear with recognition that addictive and criminal behavior often are maintained through positive reinforcement, and that negative reinforcement of behavior often is benign and beneficial to the persons involved. In addition, most of the phenomena identified with positive psychology that Wiegand and Geller propose to embrace entail more subtle and complex combinations of behavioral principles than these authors acknowledge. Wiegand and Geller also propose to accommodate vernacular assumptions in ways that separate their approach from its conceptual base; this risks impairing the effectiveness of their work whether or not its marketability would be improved.     

Maternal socialization of children’s positive affect regulation: Associations with children’s savoring,dampening, and depressive symptoms

Maternal socialization of positive affect (PA) is linked to children's regulation of positive and negative emotions and the development of psychopathology. However, few studies have examined multiple types of emotion socialization as related to children's PA regulation and depressive symptoms. The current study examined how mothers’ socialization of children's PA regulation was related to children's PA regulation, and if children's PA regulation mediated the association between maternal socialization and children's depressive symptoms. Ninety‐six mother–child dyads (children aged 7–12) completed questionnaires and a five‐minute discussion about a positive event the child previously experienced; 76 dyads completed surveys again five months later. Partial correlations, controlling for child age and gender, indicated associations between maternal PA socialization and child PA regulation. Moderated mediation models suggested that maternal modeling of savoring predicted Time 2 child depressive symptoms via children's own savoring, which was moderated by Time 1 depressive symptoms. The moderated path indicated that only for children who reported higher depressive symptoms at Time 1, higher levels of savoring predicted lower depressive symptoms at Time 2. These results underscore the importance of examining multiple types of PA socialization and child PA regulation to predict children's depressive symptoms longitudinally.     

The experience of smoking in recovery settings: an ecological momentary assessment pilot study

ABSTRACT

Smoking continues to be the leading cause of preventable death in the United States, and people with substance use disorders (SUD) smoke at higher rates compared to their non-using counterparts. Individuals with SUDs may have different emotional experiences and expectancies than those without. The current study explored the relationship between smoking and emotional experiences among residents in recovery homes, a population that little is known about regarding their tobacco addiction. Using ecological momentary assessment (EMA), significant emotional differences were found between nicotine users and nonusers. Implications of these findings could help in the development of interventions directed toward reducing smoking cessation.

Emotional Memories Stemming From a Crisis: A Snapshot of AIDS Activism in Washington,DC (1981–1986)

Emotional memories—described in this article as conscious, protracted memories that reference emotional events from the past—provide powerful qualitative data for social analysts. The reconfigured concept “emotional memories,” a neuroscientific term, is utilized to help describe the long-term effects of affective, historically situated marginalization. The author highlights emotional memories of African American lesbian, gay, and bisexual activists involved in the early years of the AIDS crisis in Washington, DC, and connects these memories to documentation in the archives, which illuminate the source and power of these emotions. The author additionally uses an interdisciplinary lens to sociologically understand collective, yet individual, emotional responses to an epidemic.     

Bootstrap tests for multivariate directional alternatives

Tests on multivariate means that are hypothesized to be in a specified direction have received attention from both theoretical and applied points of view. One of the most common procedures used to test this cone alternative is the likelihood ratio test (LRT) assuming a multivariate normal model for the data. However, the resulting test for an ordered alternative is biased in that the only usable critical values are bounds on the null distribution. The present paper provides empirical evidence that bootstrapping the null distribution of the likelihood ratio statistic results in a bootstrap test (BT) with comparable power properties without the additional burden of assuming multivariate normality. Additionally, the tests based on the LRT statistic can reject the null hypothesis in favor of the alternative even though the true means are far from the alternative region. The BT also has similar properties for normal and nonnormal data. This anomalous behavior is due to the formulation of the null hypothesis and a possible remedy is to reformulate the null to be the complement of the alternative hypothesis. We discuss properties of a BT for the modified set of hypotheses (MBT) based on a simulation study. The resulting test is conservative in general and in some specific cases has power estimates comparable to those for existing methods. The BT has higher sensitivity but relatively lower specificity, whereas the MBT has higher specificity but relatively lower sensitivity.

Measuring What Matters: Achieving Consensus on a Positive Aging Indicator Set For Ireland

The objective of this study was to measure consensus among expert stakeholders on a set of positive aging outcome indicators in Ireland. Stakeholders from academic, public, and voluntary sectors and older people participated in a 3-round, online Delphi study to evaluate indicators for participation, security, healthy aging, attitudes to aging, and information access. Evaluation criteria included: acceptability, utility, accessibility, ranking, and balance and coherence. Consensus was achieved on 56 key indicators that are aligned with action areas in the National Positive Ageing Strategy. These indicators will be reported on a biannual basis to monitor progress in positive aging in Ireland.
